Roulette Ball ki Physics

Ball

Pehle haathi daant, phir ivorine (ek celluloid), ab aam taur par Teflon ya waisa hi polymer, 18 se 21 mm chaudi, kuch grams ki. Casinos kai sizes rakhte hain aur badalte rehte hain, kyunki chhoti, halki ballsaamanBallChhoti ball jo rotor ki ulti disha mein track par chhodi jaati hai. Aaj ki balls ivorine ya Teflon ki hoti hain, 18–21 mm.Poora padhein → fretssaamanFretWheel par do pockets ke beech ka metal divider.Poora padhein → par zyada uchhalti hai aur zyada door bikharti hai, jo house ke liye achha hai. Ball non-magnetic honi chahiye aur uski golai check ki jati hai; jo ball poori gol nahi hoti woh jaldi aur bina tarteeb gir jati hai.

Track par

Jhuke hue gol track par ball ko ghoomte rehne ke liye mv²/r ka centripetal force chahiye. Jab tak ball tez hai, track ki deewar yeh deti hai. Ball slow hoti hai toh zaroori force ghatta hai, jab tak jhukaav ke saath gravity ka andar wala hissa us had se zyada na ho jaye jo geometry sambhaal sakti hai, aur ball ludhak jati hai. Critical speed sirf track ke radius aur angle par nirbhar hai, isliye kisi ek wheel par drop speed har spin mein lagbhag constant rehti hai, aam taur par 1 se 1.3 m/s.

Deceleration ka pattern

Rolling friction lagbhag constant rate se energy hatata hai; ball tez ho toh hawa ka drag zyada hatata hai. Dono milkar har lap ko pichhle se ek predictable maatra lamba bana dete hain. Lagatar do ya teen lap times naapkar aap friction aur drag constants fit kar sakte hain aur andaaza laga sakte hain ki ball kis lap par giregi. Saaf wheel par yeh andaaza second ke kuch dasve hisse tak sahi hota hai; timing-based predictors yahi naapte hain, aur deceleration page hisaab dikhata hai.

Bikhraav har wheel ke liye drop point ke neeche wale pocket ke relative aakhri pocket ke distribution ke roop mein naapa jata hai; modern wheels par yeh aam taur par dono taraf 10 se 15 pockets tak phailta hai, aur kuch wheels do ya teen modes dikhate hain kyunki kuch khaas deflectors se zyada baar takkar hoti hai.

Player ke liye iska matlab

Drop tak sab kuch siddhaant mein jaana ja sakta hai aur bina equipment aur der wali bets ke practice mein bekaar hai. Drop ke baad sab kuch is tarah design kiya gaya hai ki jaana na ja sake. Nateeja aisa game hai jiske outcomes isliye random nahi hain ki physics random hai, balki isliye ki unhe predict karne ke liye zaroori jaankari track aur pocket ke beech mit jati hai.
